licht.wissen 09Refurbishment in Trade, Commerce and AdministrationProduction plant lightingWorkplace lighting in industry and trade needs to meet the highest quality and safety standards. The right lightdemonstrably helps reduce error rates and absenteeism.Explain to your customers that good lightingtechnology is a worthwhile investment:modern solutions are considerably moreefficient than old installations and reducemaintenance costs. Numerous studies alsoshow that good light and higher illuminancecan boost productivity in a company: Older employees generally require more light.Younger employees are also more focusedand productive.There is a measureable downturn in errorrates.Work-related accidents and absenteeismdecrease sharply.[25 + 27] Good work lighting promotes motivationand performance, guards against accidentsand saves energy and costs.[26] Combining high luminous intensitywith a long life, LEDs are in increasingly widespreaduse in production premises.Luminaire selectionFor the general lighting in a production hallup to 6 metres high, wide- and narrowbeamcontinuous rows should be installedparallel to the main viewing direction. Supplementaryworkplace luminaires need to betailored to the specific visual tasks performed.Alternatively, dedicated task arealuminaires can be installed at workplaces.For halls over 6 metres high, high-bay reflectorluminaires are the right choice.Lighting in industry and trade often needs tosatisfy exacting requirements in terms ofelectrical, thermal and mechanical reliability.Explain the luminaire protection classes anddegrees of protection required and find outabout any fire and explosion protection regulationsthat need to be observed as well asthe mechanical loads to which luminaires areexposed. Make sure that standard-compliantemergency and safety lighting is installed.Glare-free lightingAs a general rule, ergonomically correctlighting needs to be glare-free and shouldhave very good colour rendering properties,especially where demanding visual tasksneed to be performed. Neutral or daylightwhite light is a time-honoured solution.Guidance on design is provided by DINEN 12464-1 and workplace regulations(Arbeitsstättenrichtlinien).LEDs in production premisesLED luminaires are in increasingly widespreaduse in production premises. With along life and extremely efficient, they deliverinstant flicker-free uniform light and are imperviousto vibration. Further significantsavings can be achieved by harnessingdaylight, e.g. through a saw-tooth roof ordomelights. The artificial lighting is then regulatedto supplement daylight only as required.That saves electricity costs and reducesthe need for maintenance.More information on this subject canis available in the booklet licht.wissen 05“Industry and Trade” while further informationabout safety lighting is found in thebooklet licht.wissen 10 “Emergency lighting,safety lighting”.252226

Special LED luminaires have beenspecifically developed for this purpose. They maximisesavings potential while at the same time delivering sufficientnet luminous flux in an appropriate light distributionpattern to replace an old reflector luminaire fitted withhigh-pressure mercury vapour lamps (e.g. with 250 Wratings). As of 2005, this type of lamp is no longerallowed to be placed on the EU market because of itspoor energy balance (Commission Regulation245/2009/EC).Nevertheless, lighting design evidence is still required toensure that health and safety requirements are met. Ifsufficient daylight is available, even more energy can besaved in some cases by constant lighting regulation.2723
